Answer:
Jennifer paid $108
Step-by-step explanation:
First you have to figure out how much Jennifer's parents paid. In order to do that you will have to do:
180 * 40 = 7,200 Then do: 7,200 / 100 which is 72 OR YOU CAN:
40 / 100 = .40 Then do : .40 * 72 which is 72
So Jennifer's parents paid $72.
So now you figured out how much Jennifer's parents paid, so to figure out how much Jennifer paid do:
180 - 72 which is $108.
This is how you know how much did Jennifer pay.
Let
x----------------> <span>feet of yarn of Becky
y----------------> </span><span>feet of yarn of James
we know that
4 2/8------> 4 1/4--------> (4*4+1)/4-----> 17/4
1 5/8------> (1*8+5)/8-----> 13/5
x+y=4 2/8-------> x+y=17/4----> equation 1
x=1 5/8--------> x=13/5------> equation 2
substitute 2 in 1
[13/5]+y=17/4------> y=(17/4)-(13/5)----> y=[5*17-4*13]/20
y=(85-52)/20-----> y=33/20----> y=1.65-----> y=1 65/100----> y=1 13/20
the answer is
</span><span>james have 1 13/20 ft of yarn</span>
